Description
Die vorliegende Erfindung betrifft im Allgemeinen Airbags und Sensoren, die verwendet werden, um die Airbagauslösung zu kontrollieren, und im Besonderen Sensoren, die die tatsächliche Auslösungssequenz überwachen.The The present invention relates generally to airbags and sensors, which are used to control the airbag deployment, and in particular, sensors that monitor the actual firing sequence.
Airbags wurden ursprünglich als ein passives Rückhaltesystem entwickelt, aber es ist bekannt, dass sie am besten in Kombination mit Sicherheitsgurten und anderen Sicherheitssystemen funktionieren. Wenn der Fahrzeuginsasse so positioniert ist, dass eine Airbagauslösung gefährlich sein könnte, wird dies als „Out-of-Position" des Insassen bezeichnet. Es wurden verschiedene Systeme entwickelt, um einen „Out-of-Poisition"-Insassen zu erkennen. Sensorsysteme, die dazu entworfen sind, um die Position des Insassen zu erkennen, erfordern oft eine ununterbrochene Überwachung, so dass im Fall eines Zusammenstoßes die Position des Insassen bekannt ist. Sensorsysteme, die dazu entworfen sind, die Position des Insassen zu erkennen, wurden auf der Grundlage von Ultraschall-, optischen oder Kapazitätssensoren vorgeschlagen.airbags were originally as a passive restraint system developed, but it is known that they are best in combination work with seatbelts and other security systems. When the vehicle occupant is positioned so that an airbag deployment can be dangerous could, will this is referred to as the "out-of-position" of the occupant. Various systems have been developed to detect an "out of poisition" population. which are designed to detect the position of the occupant, often require uninterrupted surveillance, so in case a collision the position of the occupant is known. Sensor systems designed to are to recognize the position of the occupant were based proposed by ultrasonic, optical or capacitance sensors.
Ansätze nach dem Stand der Technik versuchen auf der Grundlage von verschiedenen Sensoren, den Abstand zwischen dem Airbag und einem Fahrzeuginsassen zu bestimmen, bevor der Airbag ausgelöst wird. In vielen Fällen ist der Fahrzeuginsasse in dem Augenblick, in dem die Entscheidung, den Airbag auszulösen, gefällt wird, nicht zu nahe am Airbag, aber aufgrund der Rate, mit der sich der Insasse dem Airbag annähert, ist der Insasse zu nahe, wenn der Airbag tatsächlich auslöst. Um diese Situationen in den Griff zu bekommen, sind kompliziertere Sensoren und Algorithmen erforderlich, um zu versuchen, die Position des Insassen vorherzusagen, wenn der Airbag tatsächlich ausgelöst oder fast vollständig ausgelöst ist. Das ideale Airbagauslösungssystem funktioniert so, dass der Airbag vollständig oder fast vollständig auslöst, bevor der Insasse auf den Airbag trifft.After approaches Try the state of the art on the basis of different Sensors, the distance between the airbag and a vehicle occupant to determine before the airbag is triggered. In many cases the vehicle occupant at the moment when the decision, the Trigger airbag, like is not too close to the airbag, but due to the rate at which the occupant approaches the airbag, the occupant is too close when the airbag actually triggers. To these situations in to get a handle are more complicated sensors and algorithms required to try to predict the position of the occupant when the airbag actually triggered or almost completely triggered is. The ideal airbag deployment system works so that the airbag completely or almost completely triggers before the occupant meets the airbag.
